[BRIEFING.COM] The S&P 500 (+0.15%) is in second place on Friday afternoon, poised to end the week -0.2% lower.

Briefly, S&P 500 constituents Sandisk (SNDK 481.74, -21.70, -4.31%), West Pharma (WST 236.00, -11.78, -4.75%), and United Rentals (URI 922.79, -33.22, -3.47%) dot the bottom of the standings. SNDK slides as Samsung’s denial of a sharp memory price increase cooled near-term pricing optimism across NAND names, triggering profit-taking in an already technically stretched stock, while URI gives back all of this week's advance ahead of next week earnings report.

Meanwhile, Fortinet (FTNT 81.97, +4.35, +5.60%) is outperforming after TD Cowen upgraded the stock to Buy this morning citing FY26 stability and AI-driven upside.
